Add Discord Bot project type with process control, config editor, and log viewer

- DiscordBotProject: new project type (discord-bot), auto-detects from main.py + cogs/
- botcontrol API: start/stop/restart/status via sudo systemctl
- botconfig API: atomic read/write of config.json; CRUD for streamers, RSS feeds,
  Mastodon accounts, and LinkedIn pages; tokens masked in GET responses
- botlogs API: tail log file (path via project_settings.bot_log_file)
- Tab partials: _tab_bot (process control), _tab_botconfig (structured editor),
  _tab_logs (log viewer with auto-refresh)
- view.php: register bot/botconfig/logs tabs with labels, icons, and groups
- app.js: bot control panel, config editor with account/page dropdowns in RSS modal,
  Mastodon accounts CRUD, LinkedIn pages CRUD; audit labels/icons for all new actions
- CLAUDE.md: document Discord Bot integration, sudoers requirement, API actions
